Rembrandt: Backlight turns off automatically and LCD is still working

    • Closed Issue created by Peter Weber @hoschi_nullptr

    Likely duplicate of #2935 (closed)

    Hello!
    I'm not able to comment on #2935 (closed). Probably to false positive spam protection:

    Your comment could not be submitted because your comment has been recognized as spam. please, change the content to proceed..

    Any attempt to bypass it failed. I'm sorry if I'm creating even more noise.

    Brief summary of the problem:

    When launching a game like Counter-Strike 2 or OpenRA there is a chance of 10% - 20 % that the backlight turns off. The only workaround I'm aware to get it on again is a suspend and resume i.e. Fn+4 and Fn.

    Hardware description:

    • Laptop: ThinkPad X13 Gen3
    • CPU: AMD Ryzen™ 7 PRO 6850U
    • GPU: Rembrandt [Radeon 680M]
    • System Memory: 16 GB 32 GB (# edit: new mainboard fresh from Lenovo, 2023-12-27)
    • Display(s): AU Optronics, 0xa79d (HiDPI 2560x1600)
    • Type of Display Connection: eDP

    System information:

    • Distro name and Version: Archlinux
    • Kernel version: 6.5.9 (# edit: 6.6.8, still happening)

    How to reproduce the issue:

    1. Launch a game which causes some kind of workload on the GPU
    2. Repeat until the backlight goes off (requires probably ten or more tries, if occurred once less likely)

    Further affected users -> my original intent was adding that list to #2935 (closed)

    Thank you :slight_smile:

          Great! looking forward to more tests on games. Just curious, is this bug affecting any AMD-based gaming handhelds?

        • ZHU Yuhui
          ZHU Yuhui @zhuyuhui97 ·

          And in my case this just appear more frequent in games but also in other apps.

          I am also curious about what TCON chip the AU panel is using. Have you run the psr.py just like the developers indicated?

          Mainboard broke and I got a replacement. Sorry for delay. At least I know that it is definitely not an issue with the mainboard :upside_down:

          And in my case this just appear more frequent in games but also in other apps.

          Yep.

        I'm now on linux-firmware 20240115.9b6d0b08-1 and see what happens.

        Happened right now again.
        Newer firmware is not a fix.

        I was able to use the device for around 12 hours without a glitch since it happened last time.

           current delta between boottime and monotonic clocks, this works only for messages printed after last resume.

          For this issue specific to Rembrandt and you can still reproduce please upgrade to the latest DMCUB if you have an older one. The current version is 0x4000044. You'll see it in your logs.

          Please also upgrade to the latest stable kernel, there have been various changes for PSR-SU policy (For example d16df040c8dad25c962b4404d2d534bfea327c6a). If this can still be reproduced I think we'll need a DMCUB trace.

          Thank you Mario. I'm testing it now and will report back in a few days.

          [    2.567649] [drm] Loading DMUB firmware via PSP: version=0x04000044

          Running with Linux 6.9.3 which should contain the commit mentioned above for some time now. Maybe I'm a little special because my HiDPI-Panel isn't often sold by Lenovo?

          It doesn't work. Backlight turns off :slight_frown:

          I've booted up around 18:27 and already at that time this message was added to the system log:

          But everything kept working. At 18:50 I've executed fwupdmgr get-devices (nothing special?) and the backlight turned off some seconds later when I switched between windows with Alt+Tab. Therefore I closed the LID and opened the LID, the backlight turned on again.

          Please note

          I've turned off suspend on LID close.

          /etc/systemd/logind.conf

          # don't suspend on lid close

          @hoschi_nullptr are you sure that it's tied to running fwupdmgr get-devices? That's really interesting if so. There are fwupd plugins that will try to use an aux channel to communicate with connected DP devices. Can you reproduce again with the same symptom? What version of fwupd? If you are sure it's fwupd caused it can you sudo systemctl mask fwupd.service and then reboot and see if it comes back again like that?

          No. I don’t think fwupd is the culprit. It happened this time right after switching the windows from the terminal to the web-browser.
          I happened previously when playing Counter-Strike 2 for some time. Or when starting Counter-Strike 2. Or when browsing the web or some other seemingly random task.

          I would suspect some state change by the GPU or similar? But I’ve no clue. The only hint is the error message from above which is printed at some random time. This time after boot, more often hours after.

          Just to make sure it's not fwupd can you mask the service? It can start up on it's own in the background too for refreshing metadata once a day. If you collect a journal (specifically; not just a kernel log) you can check if anything else was activated at the same time it happens too.

          Masking fwupd.service didn't helped.

          I masked the service during the weekend and suspended the laptop.

          systemctl status fwupd.service 
○ fwupd.service
     Loaded: masked (Reason: Unit fwupd.service is masked.)
     Active: inactive (dead)

          Today opened the display and the laptop resumed. Opened Evolution, opened Epiphany, started to login on a website and seconds later the backlight turned off. I've suspended and resumed again to get the backlight on again.

          This time the kernel logged a trace right a the time were the backlight turned off:

          Is it possible to add a quirk for this display model?
          I guess it will be never fixed and depends on the HiDPI-Display solely.

        We cannot trust dmesg -T according to the man page (doesn't support suspend/resume). This message was printed a day before (Tuesday) but my display backlight went off today (Wednesday).

        So this message is actually some kind of precursor?

          Can you confirm using amdgpu.dcdebugmask=0x10 can help your issue? There will be some power consumption impact, but maybe we do need to quirk your machine if PSR is still leading to problems.

        • Peter Weber

          It works. Tested for months with it.

          May I dare to add another question? This is the output of psr.py on my machine without amdgpu.dcdebugmask=0x10:

          ./psr.py

○ ID String: 06-96
○ PSR Status: 00-00-02

          Is guess there is something special with my AU Optronics, 0xa79d (HiDPI 2560x1600). Then I read again your comment about d16df040c8dad25c962b4404d2d534bfea327c6a which says:

          We have observed that there are quite a number of PSR-SU panels on the
market that are unable to keep up with what user space throws at them,
resulting in hangs and random black screens. So, make damage clips
support configurable and disable it by default for PSR-SU displays.

          How I can read the content of the variable is_psr_su? Does it maybe contain not expected value?

          You could try to instead use amdgpu.dcdebugmask=0x200 which will explicitly turn off PSR selective update instead of all of PSR but I'm not sure that will really change much if you haven't changed damage clips.

          Thank you! I will try amdgpu.dcdebugmask=0x200 and report again. Likely in some days.

          If that doesn't help we've still the option for a quirk.

        I'm closing this.

        @superm1

        Rational

        • With Linux 6.10 and 6.11 the option amdgpu.dcdebugmask=0x200 turns off PSR selective update and I had no issues.
        • With Linux 6.12 graphical glitches appeared when amdgpu.dcdebugmask=0x200 is used.
        • But with Linux 6.12 PSR-SU now seems to work reliable without amdgpu.dcdebugmask=0x200. My display seems not to turn off randomly anymore.

        The last one fixed this issue.

        It is fine now.

          Sadly Linux 6.13.x seems to have reintroduced this bug.

          I've to use amdgpu.dcdebugmask=0x200 to set DC_DISABLE_PSR_SU. Without out this the backlight goes off likely once in four hours.

          But BTW we are potentially going to turn off PSR-SU by default.

          Somehow, I would be fine with PSR-SU turned off by default. I need my own Unicode plane to express my emotions about that. But I would be fine :relieved: :disappointed_relieved:

          I can bisect, but my time is limited to weekends. Considering that I need four to eight hours for one test, I can test one or two patches per week. Would it be possible to limit the number of patches to some interesting patches in gpu/drm/amd/${SOME}?

        I've switched back from PSR-SU to PSR:

        [    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=71cd6d2c-f53f-4625-85b7-2d38d39cbb4e rw loglevel=3 quiet amdgpu.dcdebugmask=0x200

        DC_DISABLE_PSR_SU

        But # ./psr.py prints:

        I'm confused. I assumed some different values for PSR Status?

        This is printed with 6.13.5 to dmesg when PSR-SU fails and turns the backlight off. Or it is printed to dmesg some time after, because I need to suspend and resume to read the screen.

        The message is printed between the suspend and resume messages. But as far as I know timestamps around suspend and resume aren't reliable.

        @superm1 Would be nice if you close this issue when PSR-SU is actually turned off by default.
